How is the Qatar World Cup Stadium Lighting Designed?

As a sports event held every four years, each World Cup can trigger a global upsurge, and this year's World Cup, which is called "the most expensive in history", has attracted even more attention. According to the statistics of CNN and "Forbes", Qatar The total cost of the World Cup is 220 billion US dollars, while the total cost of all past World Cups is only 44.3 billion.

As an important venue for the World Cup, football stadiums will not only affect the performance of athletes but also affect the viewing experience of on-site or online fans. I believe that many lighting people will be awakened by the Qatar World Cup stadium, which was built with huge sums of money when they watch the game. So take this opportunity, let's talk about what is the judging criteria for an excellent football field lighting system and how to arrange it Light, what kind of lights are used in the football field, etc.

Regarding lighting design, we have always emphasized the user-oriented benchmark, that is, setting based on the user's experience. Therefore, the lighting quality of the football field depends on the athletes and referees, the on-site audience, and the audience in front of the TV. From a professional point of view, it can be divided into illuminance level, illuminance uniformity, and glare control degree.

1. How to Judge the Lighting Level of a Football Field?

An excellent football field lighting system must realize multiple functions at the same time, which is also an important criterion for judging the lighting level of a football field.

First, good lighting conditions must be provided for players to fully demonstrate their skills;

Second, let the referees make clear judgments;

Third, let the audience from all angles clearly see the live game and live big screen reports;

Fourth, the requirements for on-site recording and TV relay equipment must be met;

Finally, the stated parameters must be respected, taking into account aspects such as the economic needs of light and the light pollution situation.

In order to meet the above requirements, the following points should be noted.

First of all, we must be clear that in a football stadium, the lighting level of the players is not the same as that of the spectators.

Athletes' visibility is related to both vertical and horizontal illuminance. The vertical illuminance depends on the projection direction and position of the floodlight. Since the horizontal illuminance is easy to calculate and measure, the recommended value of the illuminance refers to the horizontal illuminance.

The number of spectators varies greatly depending on the stadium, and the viewing distance is related to the capacity of the stadium, so the illumination required by the stadium increases as required.

Secondly, in order to provide better visual effects, the illuminance uniformity, brightness uniformity and three-dimensionality (horizontal and vertical relative imaging evaluation) of football field lighting are very important.

The horizontal/vertical illuminance standard calculation grid is an "examination paper" for accurately measuring and calculating the lighting level of football fields.

Poor lighting glare on the football field will cause visual discomfort to the players, and will also reduce the image quality of the camera broadcast. To avoid glare, the light angle setting of the field plays a pivotal role.

Improper use of floodlights will interfere with athletes, especially goalkeepers. Therefore, lighting design must be strictly in accordance with standards.

The distribution of light must take into account the setting of the camera position in order to ensure that high-quality game images are transmitted to the eyes of the audience. For example, the vertical illuminance in the direction of the camera should meet the vertical illuminance requirements of all cameras in the field.

Generally speaking, the lighting of the football field is divided into being arranged around the ceiling of the stands (that is, the so-called linear light strip lighting, but the premise is that there is a stadium with spectator stands) and grouped and installed on the columns around the stadium, and then adjusted according to the level of the venue. The number and power of lamps and lanterns (so-called four-corner arrangement, multi-pole arrangement).

Since the current broadcasts are all "HDTV broadcasts", the vertical illumination requirements are extremely high: the direction of the main camera on the rostrum is 2000lx, and the direction of the secondary camera behind the goal is 1400lx! Therefore, there need to be lights shining into the field in all directions.

In order to protect the players’ eyes from being blinded when looking at the golf ball, there is a regulation: it is not allowed to install lights in the extension line of the baseline and the area behind the goal, which is the area of the "red X" in the picture below. (Even if there are lights installed, they can only be turned on during performances and other applications. These lights cannot be turned on during football games!)

Therefore, it was necessary to install lights around the perimeter, and several areas could not be installed... Finally, a large number of lights were concentrated in the four corners of the site. In this way, it became an improved version of the "four towers".

3 What Lights Are Used In Football Stadiums?
The LED sports lights for football stadiums should be high efficiency, high lumen, great uniformity, low glare, flicker-free.

LED lights can be used as the lighting source of the football field. The choice of the light source is determined by the time of use per year, the initial investment of the project and the maintenance cost. Usually use 1000W and 1500W led floodlights, and adjust the number and angle of the lights through different installation positions to meet the design standards.

LED stadium lights have the advantages of professional light distribution technology and stable lighting performance. The continuous development of LED sports lighting technology also makes the operating costs of sports venues more attractive than before. It is more green and efficient than traditional metal halide lamps and other lighting equipment. Environmental friendly. Stadiums that install LED sports lighting systems can save 75% to 85% of total energy costs, saving many unnecessary costs for stadiums in the subsequent treatment and maintenance of sports venues.
